To find the perfect blush, choose a shade that matches your skin's undertone. Use a blush that enhances or balances the colours already naturally present in your skin. If your skin takes on colour easily, as with oily skin, chances are your undertone is gold or yellow. If your skin reddens easily, your undertone is likely pink or red. If your skin tone is darker, your undertone is probably plum or blue.
Golden or yellow undertone: Choose orange or reddish pink. This highlights and gives a healthy glow.
Pink or red undertone: Stick to a light pink to complement your natural colour, or try peach or mocha to neutralise redness.
Plum or blue undertone: Choose a vibrant orange or pink that stands out from your skin.
